Doubly-fed induction generator modeling and control in DigSilent PowerFactory

Several computer programs exist to carry out dynamic simulations and this study will focus on one of them, namely DigSilent PowerFactory. It offers two built-in models of doubly-fed induction generator. A new model has also been developed, based upon a controllable voltage source. These three models are compared, in terms of dynamic behavior and simulation time. One of them is then used to study the impact of an input control signal based on the single machine equivalent method. This signal provides power oscillation damping.
